Description

Technical Field

[0001] The invention belongs to the technical field of smoke pipes for water heaters, and specifically discloses a smoke pipe for installing a gas-fired heating water heater. Background Art

[0002] A gas-fired heating water heater is a device that uses natural gas, liquefied petroleum gas, city gas or biogas as fuel to heat water through a burner to achieve home heating and provide domestic hot water.

[0003] The smoke pipe of a gas-fired hot water boiler is an important part of the combustion system. It is responsible for directing the smoke generated by combustion from the furnace body to the outside, while allowing outdoor air to enter the furnace body to maintain the oxygen supply required for combustion. The structural design of the smoke pipe is crucial to ensure combustion efficiency and safe operation. The smoke pipe is usually made of high-temperature and corrosion-resistant materials such as stainless steel or coated metal. It can be a single-tube or double-tube structure. The double-tube smoke pipe usually includes an inner tube and an outer tube. The inner tube is used to discharge smoke, and the outer tube is used to introduce air. This design helps to achieve pressure balance, ensuring that the smoke can be discharged smoothly while preventing external cold air from entering the furnace body.

The bottom of the sealing rubber block 708 can push the pressing installation ring 707 downward, so that the pressing installation ring 707 can compress the pressing installation spring 706. When the clamping seal block 709 reaches the bottom of the sliding groove 704, the splicing tube 8 is rotated clockwise. After the splicing tube 8 rotates, it can drive the sealing rubber block 708 to rotate. After the sealing rubber block 708 rotates, it drives the clamping seal block 709 to rotate. When the clamping seal block 709 rotates to the splicing clamping groove 703 , loosen the splicing tube 8, at this time, the sealing rubber block 708 can be driven to move upward under the action of the pressing installation spring 706, so that the locking sealing block 709 can be locked in the inside of the splicing locking groove 703 to complete the splicing of the splicing tube 8.

When the smoke pipe splicing is completed, the installation driving sliding sleeve 903 is first slid upward, and then the sliding engagement sealing plug 904 can be driven to move upward, so that the installation driving sliding sleeve 903 can be used to compress the sealing pressure spring 902, and the installation driving sliding sleeve 903 is loosened. Under the action of the sealing pressure spring 902, the installation driving sliding sleeve 903 is driven to move downward, so that the sliding engagement sealing plug 904 can be moved downward, and the sliding engagement sealing plug 904 is used to block the sliding groove 704, thereby completing the sealing.

[0036] Working principle: When installing the smoke pipe, first rotate the rotating handle upward, so as to drive the pulling connecting rod to move upward. When the pulling connecting rod moves upward, the sliding mounting ring can be driven upward by rotating the sleeve, and the sliding mounting ring can drive the mounting sleeve to move upward. At this time, slide the sliding hollow sleeve upward, and set the mounting sleeve on the outside of the connecting mounting pipe. Then slide the sliding hollow sleeve downward and rotate the sliding hollow sleeve, so that the threaded connecting sleeve can be screwed on the outside of the threaded fixing seat. At this time, release the rotating handle, and the pressing sliding mounting ring can be driven under the action of the pressing sealing spring, so that the mounting sleeve can be tightly pressed against the outside of the connecting mounting pipe. At this time, the sealing ring pushes the sealing pressing sleeve to move upward, thereby compressing the sealing pressing spring. Therefore, the reaction force of the sealing pressing spring can be used to press the sealing pressing sleeve tightly against the top of the sealing ring, thereby playing a sealing role.

[0037] When the smoke pipe is spliced, first the installation driving sliding sleeve is slid upward, and then the sliding clamping sealing plug block can be driven to move upward, so that the installation driving sliding sleeve can be used to compress the sealing pressing spring, the clamping sealing block is aligned with the sliding groove, and the sealing rubber block at the bottom of the splicing pipe is inserted into the top of the installation sleeve groove. The bottom of the sealing rubber block can push the pressing installation ring downward, so that the pressing installation ring can compress the pressing installation spring. When the clamping sealing block reaches the bottom of the sliding groove, the splicing pipe is rotated clockwise, and the rotation of the splicing pipe can drive the sealing rubber The block rotates, and the sealing rubber block rotates and drives the engaging sealing block to rotate. When the engaging sealing block rotates to the splicing engaging groove, the splicing tube is released. At this time, the sealing rubber block can be driven to move upward under the action of the pressure installation spring, so that the engaging sealing block can be engaged in the inside of the splicing engaging groove. At this time, the installation driving sliding sleeve is released, and the installation driving sliding sleeve is driven to move downward under the action of the sealing pressure spring, so that the sliding engaging sealing plug block can move downward, and the sliding groove is blocked by the sliding engaging sealing plug block, thereby completing the sealing;

[0038] When disassembling the pipeline, first press the splicing pipe downward to make the locking sealing block move to the bottom of the splicing locking groove, and rotate the splicing pipe counterclockwise to drive it to slide inside the installation sliding groove. When the locking sealing block slides into the sliding groove, the locking sealing block can be slid out along the sliding groove to complete the splicing and disassembly.
